矮化密植栽培是果树生产的发展方向,也是果树生产现代化的标志。目前全国及世界上许多主要苹果生产国都在研究、推广苹果矮化密植栽培技术。我省苹果矮密栽培已经日渐受到重视,科研单位及生产单位都在进行研究和推广这项技术。但是,由于矮化苹果苗木难繁殖,能投入生产上应用的数量有限,从而严重地阻碍了矮化密植栽培技术的快速普及。苗木缺乏已经成了果树生产上的限制因素。研究并迅速繁育矮化苹果苗是当前需要解决的迫切问题。
Dwarf and dense planting is the development direction of fruit tree production, but also a symbol of the modernization of fruit trees. At present, many major apple producing countries across the country and in the world are studying and promoting apple dwarf planting techniques. Apple cultivation in our province has become increasingly valued cultivation, research institutes and production units are conducting research and promotion of this technology. However, because dwarf apple seedlings difficult to breed, can be put into production a limited number of applications, which seriously hampered the rapid spread of dwarf and close planting techniques. Lack of seedlings has become a limiting factor in the production of fruit trees. Research and rapid breeding dwarf apple seedlings is an urgent problem to be solved.
